I don't really watch sports much, when I do it's usually just on TV by coincidence. Since rugby is pretty much THE sport here it's on a lot, and although I don't really know all the rules, it's still fairly entertaining. Same with golf, if it's on I might watch. Soccer's fairly enjoyable to watch (played it a lot when I was younger), but again I won't go looking for it. Table tennis is probably my favourite sport (to play as well as watch) so I'd watch that if it ever came on.
Other than that I don't actively watch sports other than the Olympics and FIFA.
